Abstract
The present invention relates to an air cleaner for a vehicle, and more particularly, to an air cleaner for a vehicle, comprising: a housing including a body having an upper portion thereof opened and an intake port formed on one side thereof and a cover provided on an upper portion of the body, A filter unit disposed between the cover and configured to filter foreign substances contained in the air introduced through the intake port, and a sound absorbing member provided on the surface of the housing. Accordingly, the noise absorbing member provided on the housing attenuates the noise, so that the resonator can be omitted from the intake system of the vehicle, thereby improving the space utilization of the engine room, reducing the weight of the vehicle and improving the fuel economy of the vehicle, The cost is reduced and the number of components of the intake system is reduced, thereby improving the assemblability.
Description
More particularly, the present invention relates to an air cleaner for a vehicle, and more particularly, to a vehicle air cleaner provided with a sound absorbing member inside a housing of an air cleaner to attenuate noise, To a vehicle air cleaner capable of improving the space utilization of the vehicle, fuel efficiency of the vehicle, assembling performance of the vehicle, and reducing manufacturing cost of the intake system.
1, in the first section, the pressure near the exhaust valve and the internal pressure of the combustion chamber of the cylinder are equal to the pressure of the intake valve So that the pressure fluctuation is propagated toward the intake valve by the pressure difference to form a part of the intake noise.
In the second section, as the piston is lowered to the point of time when the intake valve closes at the time when the exhaust valve is closed (Max. Valve Lift), the vacuum is formed in the combustion chamber and the mixture is sucked through the intake port. The intake port is not filled with a large amount of the mixture that is sucked into the combustion chamber due to the inertia of the intake port, so that the negative pressure is formed because the pressure of the intake port is lower than the average intake time of the intake port at that point.
In the third section, the passage of the intake flow is narrowed as the valve is closed from the time when the intake valve is opened to the highest level, and the amount of the mixture flowing into the intake port portion is larger than the flow rate. Which is higher than the total time average to form a static pressure.
The fourth section is a section from the point of time when the intake valve is closed to the point of time when the intake valve of the next cycle is opened and the pressure of the intake port formed through the above- A surge tank, an air cleaner, an air duct, and an intake orifice), and a residual pressure fluctuation due to interference between traveling waves.
In this way, when the mixed air supplied to the engine of the vehicle is filtered while passing through the air cleaner, mixed with the fuel and then introduced into each cylinder in the engine, the air is introduced into the cylinder So that the inflow air collides with the wall surface of the cylinder or the piston and flows backward while pressure is generated in the direction opposite to the inflow of air, so that a pulsating wave is generated and noise is generated.
Further, noise caused by the opening and closing of the intake valve for sucking air into the cylinder is a factor for amplifying the noise of the intake system, thereby reducing the quietness of the vehicle.
In order to reduce the noise, a resonant resonator is installed on the intake system as shown in FIG. 2 for tuning the intake system to a specific frequency.
That is, in the conventional intake system, a resonator having an air cleaner and an expansion pipe formed at an intake port connecting the intake manifold to the intake manifold connected to the engine and uniformly distributing air to the engine is provided, so that the intake / The resonance frequency of the mixer due to the reciprocating motion of the mixer is removed.
However, if the resonator is installed in the intake port of the intake system as described above, not only the engine room becomes complicated but also the space utilization of the engine room is restricted due to the volume occupied by the resonator.
SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a sound absorbing member for reducing noise in an air cleaner itself, And it is an object of the present invention to provide an air cleaner for a vehicle which can reduce the weight of a vehicle.
Technical Solution According to an aspect of the present invention, there is provided a fuel pump comprising a body having an upper portion opened and an intake port formed on one side thereof, and a cover provided on an upper portion of the body and having an exhaust port formed on the other side opposite to the intake port A filter unit installed between the body and the cover for filtering foreign substances contained in the air introduced through the intake port and a sound absorbing member provided on the surface of the housing; .
Here, the sound absorbing member may be formed of a plurality of pieces of the housing and may be provided on the surface of the housing.
In addition, it is preferable that the sound absorbing member has irregularities formed on its surface.
It is preferable that the sound absorbing member is any one of porous fiber and porous synthetic resin.
In addition, it is preferable that the sound absorbing member is tuned in size and distribution of the pores to attenuate noise in the 50 to 500 Hz band.
Preferably, the housing has a plurality of ribs formed on an inner surface thereof, and the sound-absorbing member is attached to an end of the rib, so that a gap is formed between the inner surface of the housing and the sound-absorbing member.
The sound absorbing member may include a body side sound absorbing member provided on a surface of at least one of an outer side surface and an inner side surface of the body, and a cover side sound absorbing member provided on at least one surface of the outer side surface and the inner side surface of the cover .
According to the air cleaner for a vehicle according to the present invention, since a sound absorbing member is provided in the housing to reduce noise, it is not necessary to provide a separate resonator in the intake system.
Therefore, the resonator can be omitted in the intake system of the vehicle, so that not only the space utilization of the engine room is improved but also the weight of the vehicle is reduced and the fuel economy of the vehicle is improved.
Further, since the resonator is omitted in the intake system of the vehicle, the manufacturing cost of the intake system is reduced, and the number of parts of the intake system is reduced, thereby improving the assemblability.
